Abstract
According to an embodiment, a semiconductor memory device includes a plurality of memory blocks including first to m-th guarantee blocks, wherein m is an integer greater than 1; repair logic suitable for generating bad block information by detecting defective memory blocks among the first to m-th guarantee blocks, and determining first to m-th offset values respectively corresponding to the first to m-th guarantee blocks based on the bad block information; and an address decoder suitable for generating a block selection address by reflecting an offset value selected from the first to m-th offset values onto a block address when the block address corresponds to any of the first to m-th guarantee blocks, and by reflecting the m-th offset value onto the block address when the block address corresponds to any of the memory blocks except for the first to m-th guarantee blocks.
